I think it's old. I have watched the videos and my trucks are different. The two screws between the wheels are as per the video. I have 6 screws in the bottom of the trucks but they are all the same length (short). There are none of the long screws that hold the top plate on. The top plate with the screws between the wheels removed is held in exactly the positions that the long screws would hold it. There are 2 screws on the top of the trucks
In the right place except they are the size of spectical hinge screws and are not accessible due to the body of the engine above.
Any help would be appreciated.
